A hip but friendly spot on the main drag, L'Osteria serves heart-warming Aostian comfort fare: wild boar in pinot noir with rosemary over polenta, creamy rich fondue, and Valpellinentze (a meaty soup with cabbage, pancetta, rye bread and fontina cheese). Dine in the easy-going back room, amid globe lights and curious wood carvings.
Don't neglect the top-notch Aosta Valley wines and excellent specials.
